Abstract: The invention provides novel slate-like composite materials and methods for preparation thereof. The slate-like composite materials can be readily produced from widely available, low cost precursor materials by a process suitable for large-scale production. The precursor materials include calcium silicate, for example, wollastonite, and particulate filler materials which comprise silicon dioxide-rich materials such as quartz, mica, feldspar, sand and glass. Additives can include calcium carbonate-rich and magnesium carbonate-rich materials. Various additives can be used to fine-tune the physical appearance and mechanical properties of the composite material, such as colorants such as particles of colored materials, such as colored glass, colored sand, and colored quartz particles, and pigments (e.g., black iron oxide, cobalt oxide and chromium oxide). These slate-like composite materials exhibit visual patterns unique to slate as well as display compressive strength, flexural strength and water absorption similar to that of slate.
